Scientific Research Applications

Oxidation of Light Alkanes

Potassium trifluoroacetate plays a role in the partial oxidation of light alkanes. Research by Kalman et al. (2015) highlights the use of potassium periodate and potassium chloride for efficient methane functionalization in trifluoroacetic acid, yielding over 40% of methyl trifluoroacetate with high selectivity (Kalman et al., 2015).

Aqueous Extraction in Beverages

A study by Scheurer and Nödler (2021) found that trifluoroacetate is a widespread contaminant in beer and tea. This ultrashort-chain perfluoroalkyl substance accumulates in plant material and is present in significant concentrations in various beverages (Scheurer & Nödler, 2021).

Microwave Dielectric Studies

Lyashchenko et al. (2013) conducted microwave dielectric measurements in aqueous potassium trifluoroacetate solutions, exploring the structuring and molecular-kinetic stabilization of the hydrogen bond network. These studies provide insights into the hydrophobic hydration of trifluoroacetate ion (Lyashchenko et al., 2013).

Sol-Gel Synthesis

Research by Labeguerie et al. (2005) involves the sol-gel synthesis of K3InF6 using trifluoroacetic acid as a fluorinating agent. This study offers valuable information on the synthesis process and the structural characterization of various organic compounds (Labeguerie et al., 2005) .

Crystal Structures and Proton Dynamics

Cousson et al. (2004) determined the crystal structures of potassium and cesium bistrifluoroacetates, providing insights into strong symmetric hydrogen bonds and proton dynamics in these compounds (Cousson et al., 2004).

Metal-Free Ring-Opening Reactions

Roscales and Csákÿ (2014) described the ring-opening of epoxides with potassium trifluoroborates, using trifluoroacetic anhydride under metal-free conditions. This process is significant for its regioselectivity and ability to tolerate a range of aryltrifluoroborates (Roscales & Csákÿ, 2014).

Methane and Alkane Oxidation

Liu et al. (2021) explored the oxidation of methane to methyl trifluoroacetate, mediated by CuCl/KF/K2S2O8 in trifluoroacetic acid. This study provides insights into the effective use of potassium fluoride as a promoter in the oxidation process (Liu et al., 2021).
